BACKGROUND

The present disclosure relates to child restraints, and particularly tochild restraints adapted to be anchored to a vehicle seat to transport achild in a vehicle. More particularly, the present disclosure relates toa child restraint including a swiveling juvenile seat.

SUMMARY

According to the present disclosure, a child restraint includes a baseand a juvenile seat mounted on the base for swiveling motion about anaxis of rotation. The juvenile seat includes a seat bottom mounted on aswivel coupled to the base and a seat back arranged to extend upwardlyfrom the seat bottom.

In illustrative embodiments, the child restraint also includes aseat-back lock that is carried on the seat back and configured toinclude a hook designed to mate with a stationary seat anchor coupled tothe base whenever the juvenile seat is swiveled relative to the base toassume a forward-facing travel position. The seat-back lock and thestationary seat anchor cooperate to define a seat stop configured toprovide means for retaining the juvenile seat in the forward-facingtravel position to block rotation of the juvenile seat about the axis ofrotation.

The stationary seat anchor is fixed on the base and located to “move” ina seat-anchor guide channel formed in the seat back of the juvenile seatduring swiveling motion of the juvenile seat relative to the base. Theseat-anchor guide channel is configured to providing means for guidingthe stationary seat anchor to mate with the hook of the seat-back lockto “cure” any “misalignment” of the seat-back lock and stationary seatanchor that may exist. In illustrative embodiments, the seat back isformed to include two seat-anchor guide channels.

In illustrative embodiments, the seat back is formed to include, inseries, a first seat-anchor guide channel, a central opening exposingthe seat-back lock, and a second seat-anchor guide channel. The hookincluded in the seat-back lock is arranged to extend through the centralopening and to mate with the stationary seat anchor upon arrival of theswiveling juvenile seat at the forward-facing travel position. The firstseat-anchor guide channel receives and guides the stationary seat anchoron the base during clockwise swiveling motion of the juvenile seatrelative to the base from the left-facing entry position to theforward-facing travel position. The second seat-anchor guide channelreceives and guides the stationary seat anchor on the base duringcounterclockwise swiveling motion of the juvenile seat relative to thebase from the right-facing entry position to the forward-facing travelposition.

An illustrative seat-back lock in accordance with the present disclosureincludes a pair of pivotable hook-retainer latches. Each hook-retainerlatch is mounted on a pivot shaft segment coupled to the seat back forpivotable movement about an axis between a hook-retaining position and ahook-releasing position. In the hook-retaining position, a tip of ahook-retainer latch engages the hook to hold the book in its unlockedposition. In the hook-releasing position, the tip of the hook-retainerlatch has been moved to disengage the hook to free the hook to be movedby a hook-return spring to its locked position. The seat anchor islocated and configured to provide means for moving the hook-retainerlatches from the hook-retaining positions to the hook-releasingpositions in response to swiveling motion of the juvenile seat about itsaxis of rotation and arrival of the juvenile seat at the forward-facingtravel position.

In illustrative embodiments, a hook-release controller is coupled toeach armrest included in the juvenile seat. The hook-release controlleris configured to operate a companion linkage coupled to the hook so thata user can disengage the hook included in the seat-back lock from thestationary seat anchor whenever the operator desires to swivel thejuvenile seat relative to the base from the forward-facing travelposition to either a left-facing or right-facing entry position so thata child can be seated easily in the juvenile seat while the base of thechild restraint is fixed in a stationary position on a vehicle seat.

Additional features of the present disclosure will become apparent tothose skilled in the art upon consideration of illustrative embodimentsexemplifying the best mode of carrying out the disclosure as presentlyperceived.
